When the caret is positioned next to an element tag, a tooltip will be shown for a couple of seconds displaying the position of the caret relative to the current element context.
Here are the common situations that can be encountered:
The caret is positioned before the first children of the current node.
The caret is positioned between the start and end of two sibling nodes.
The caret is positioned after the last child of the current node.
The caret is positioned in an empty node.
The nodes in the previous cases are displayed in the tooltip window using their names. When one of them is a text node it will be presented using "..." sequence.
You can deactivate this feature by unchecking Editor / Author+Show caret positioned info checkbox. Even if this option is disabled, you can trigger the display of the position tooltip by pressing Shift+F2.
→ +The position information tooltip is not displayed if one of the modes Full Tags with Attributes or Full Tags is selected.
